4G and signal strength

[Reason077]

That's right. The iPhone will tend to select the strongest signal, regardless of which is faster. It does this to optimise battery usage, as a strong signal will mean the phone has to use less power.

Here at my flat in London I get a strong (5 bars) 2G signal, and weak (2-3 bars) 3G and 4G signals. My iPhone 6 tends to bounce back and forth between all three, which is kind of annoying.

The thing is, for data, even a weak 4G signal is still MUCH better than a 3G signal on O2. I can get 20 Mbit with a 2-bar 4G signal, but 3G will often struggle to get 1 Mbit, even with a 5-bar signal.

O2's 3G also sucks because of the long time (10 sec or more) it takes to establish a data connection, and because the data connection seems to randomly drop from time to time, requiring togging "airplane mode" in order to get it back. 4G has none of these problems!

I kind of wish I could increase the priority of 4G a bit so it would stay locked on that whenever possible instead of flipping between networks all the time. Perhaps that would mean increased power consumption, but changing networks all the time can't be great for the battery either.

I had to keep toggling my 4G on and off yesterday but today it's stuck with it on even though I'm only receiving 2 bubbles of signal with it. I used to receive 4 bubbles with 4G in my house / area and since SIM and number changeover its disappeared

Had my settings reset with still unsteady signal so I think a SIM swap is in order

Done the SIM swap today but now I've noticed that its just when I'm at home I lose 4G connection, is there a way to signal boost?

Use Tugo or place phone near a window (it's the wall's construction that blocks a signal more than glass does).

Am I right in thinking its with older constructed houses @MI5  (walls much thicker etc etc )

The thing I dont get it before I got this phone and was using my 5S I had perfect signal and 4G

Maybe network problems now then @Anonymous ?... Have you checked the mast status?

Old houses with thick walls or new houses with extra insulation - You can't win with indoors signal.....
Assumption from what you've just said is that 5s has a better modem than the 6 does.

Yes I have and its perfectly fine in my area, I have done everything I can with o2, I am now trying with Apple, I may need a new device
